Description

The present invention relates to a fitting for a window or a door, in particular electrical fitting for mounting on a door or window sash, with a mounting plate, a housing, in particular a drive housing, and fastening means for fastening the housing to the mounting plate.

Fittings for windows or doors are generally known. Such fittings can, for example, cause the door to move, often driven and provided by an electric drive unit.

When fitting such fittings, and in particular the drives provided thereby and / or therein, screws or other fastening means are usually used which remain visible after the fastening processes have ended. This can affect the overall visual impression of the fitting. Optional covers or cover plugs can only remedy this insufficiently, since a consistent design of the entire fitting is impaired, for example, by color deviations in the covers or cover plugs used.

It is also usually necessary to use tools, often even special tools, for fastening the fittings with known fastening means. This makes fitting the fittings complex and in some cases can only be carried out by specially trained specialists.

The DE 198 48 071 A1 discloses an arrangement device for a door closer, which is composed of a placement plate, a main body of the door closer and a plurality of fastening pins. The arrangement plate is attached to the door and is provided with a plurality of attachment holes. The main body is provided on one longitudinal side thereof with two extending edges which run parallel to one another and which form an elongate cavity in between, for receiving the arrangement plate. The two longitudinal edges are provided with a plurality of through openings, which correspond in position to the fastening openings of the arrangement plate. The fixing pins are received in the through holes and in the fixing holes to fix the main body to the arrangement board.

The US 3,188,682 A discloses a mounting device for a door closer with a mounting bracket. First, the mounting bracket is attached to a door leaf with screws. The door closer is then pushed onto the mounting bracket via flanges provided on the bracket, which correspond to grooves provided on the top and bottom of the door closer. The door closer is prevented from sliding away from the mounting bracket by further screws which extend through the flange of the holder and are screwed into the door closer.

The DE 10 2010 023 689 A1 discloses a mounting arrangement for a door closer with a mounting plate, the mounting plate being designed for mounting on a receptacle such as a door leaf, the door closer being fastened to the mounting plate. The mounting plate has a holding section which, for the clamping arrangement of the door closer on the mounting plate, positively engages in at least one corresponding counter holding section in the door closer.

It is an object of the present invention to remedy the disadvantages described above. In particular, it is the object of the present invention to provide a fitting for a window or a door, in which an assembly of the fitting is simplified in a simple and inexpensive manner, at the same time preferably improving an overall visual impression of the fitting and, in particular, furthermore unauthorized manipulation of the fitting can be prevented.

The above object is achieved by the claims of the present invention. In particular, the object is achieved by a fitting for a window or a door with the features of independent claim 1. Further features and details of the invention result from the subclaims, the description and the drawings.

According to one aspect of the invention, the object is achieved by a fitting for a window or a door, in particular an electrical fitting for mounting on a door or window sash, with a mounting plate, a housing, in particular a drive housing, and fastening means for fastening the housing the mounting plate, whereby as a fastening means on one of the two components, mounting plate and housing, a locking element mounted in a guide receptacle and displaceable from outside the housing when the housing is placed on the mounting plate, and a locking receptacle for receiving the locking element are provided on the other of the two components. A fitting according to the invention is characterized in that the guide receptacle is at least essentially U-shaped and has two guide legs, the locking element being arranged at least essentially between the guide legs and is displaceably guided by the guide leg, each guide leg preferably having a guide slot, in each of which a guide pin of the locking element for guiding the locking element is positively guided.

A fitting according to the invention is intended for use on a window or a door. The fitting according to the invention can preferably be designed as an electrical fitting which can be mounted on a door or window sash. Alternatively, mounting on a lintel or window frame is also possible. Movement of the door or window sash, in particular an electrically driven movement, can thus be provided by a fitting according to the invention in the assembled state.

A fitting according to the invention has a mounting plate and a housing as main elements. The housing can preferably be designed as a drive housing and thus, in other words, accommodate the drive for providing the movement of the door or window sash, for example an electric motor and preferably also corresponding transmission means. The mounting plate can be attached directly to the window or door, especially the window or door leaf. All types of fastening are possible, preferably the mounting plate can be screwed directly onto the window or door leaf. To complete assembly of the entire fitting according to the invention, the housing, in particular with a drive unit already arranged in the housing, is fastened to the mounting plate. A fitting according to the invention has fastening means for this fastening. Particularly preferably, the mounting plate and in particular the fixing elements used for fastening the mounting plate to the door or window sash are completely covered by the housing in the arranged state.

According to the invention, the fastening means comprise a locking element and a corresponding locking receptacle. Here, the locking element is slidably mounted in a guide receptacle. The latch holder in turn is provided for receiving the latch element, in particular for positively receiving the latch element. In a variant, the guide receptacle and the locking element slidably mounted therein can be provided on the mounting plate and the locking receptacle in the housing. Likewise, an inverted arrangement, that is, an arrangement of the guide receptacle and the locking element slidably mounted therein in the housing and the locking receptacle in the mounting plate can also be provided.

By receiving the locking element in the locking receptacle, a positive and / or non-positive fastening of the two components, the mounting plate and the housing, to one another is provided. This is in particular due to the fact that even when the locking element is received by the locking receptacle, the locking element remains in the guide receptacle. In other words, the locking element forms a positive connection both with the locking receptacle and with the guide receptacle. Since the guide receptacle and the bolt receptacle are located in two different components, the mounting plate and the housing, a mechanically particularly simple fastening of the housing, which can also be carried out without special tools, can be carried out in this way by simply moving the locking element mounted in the guide receptacle be provided on the mounting plate. By dispensing with additional fastening means, such as screws, nails or the like, the overall visual impression of a fitting according to the invention can also be improved.

Such a guide receptacle, which is at least essentially U-shaped, represents a particularly space-saving variant of a guide receptacle. The locking element is displaceably guided or mounted between the two guide legs and is thus at least essentially arranged between the guide legs. In other words, the installation space between the guide legs, which is no longer occupied by the mounting plate, is taken up by the locking element. Additional space for arranging the locking element is therefore not required, or at least only insignificantly. A guide slot in which a corresponding guide pin of the locking element is guided in a form-fitting manner can in each case be particularly preferably arranged in the guide legs. The guide slots in the guide legs can in turn be preferably groove-like and / or at least sectionally cylindrical. A particularly good and safe storage or guidance of the locking element in the guide receptacle can be provided in this way.

Furthermore, it can be provided in a fitting according to the invention that the guide receptacle and / or the bolt receptacle are formed at least in sections in the form of a groove. Groove-shaped in the sense of the invention can in particular mean that the guide receptacle and / or the latch receptacle can be cylindrical at least in sections. In the case of a groove-shaped guide receptacle, linear mounting and guidance of the locking element can be provided particularly easily. Through a groove-shaped design of both receptacles, both the guide receptacle and the bolt receptacle, the directions of extension of the two receptacles preferably being parallel are aligned, a fitting according to the invention can be further improved. In this special embodiment, the locking element can in particular be inserted particularly easily and securely when the locking element is moved in the guide receptacle.

In addition, it can be provided in the fitting according to the invention that the locking element can be displaced at least between a release position and a fastening position in the guide receptacle, the locking element in its fastening position engaging in a form-fitting manner in a fixing section of the locking receptacle and releasing the fixing section of the locking receptacle in its release position. In this way, a clear fixing behavior of the locking element is achieved. In its fastening position, the locking element engages in the fixing section of the locking receptacle and thus ensures the fastening of the mounting plate and the housing to one another. In contrast, in its release position, which is different from the fastening position, the locking element releases the fixing section of the locking receptacle, which enables the housing to be separated from the mounting plate. The latter can also be used during the first assembly of the fitting, since in the case of a locking element in its release position, the housing can be placed on the mounting plate, the locking element being displaced into its fastening position as a second step of the assembly and due to the positive engagement in the fixing section the latch holder fastened the housing to the mounting plate.

A fitting according to the invention is preferably formed such that the locking element has an engagement pin for positive engagement in the fixing section of the locking receptacle. Such an engagement pin can be designed, for example, as a cylinder arranged on an outside of the locking element, with an axis of the cylinder being particularly preferably designed parallel or at least substantially parallel to a direction of displacement of the locking element in the guide receptacle. A mechanically particularly simple engagement of the locking element in the fixing section can be brought about by such a specially provided engagement pin without the entire locking element having to engage in the fixing section of the locking receptacle.

Furthermore, a fitting according to the invention can be designed in such a way that the locking element can be fixed in its fastening position by fixing means, in particular grub screws, which can be actuated from outside the housing, the fixing means preferably being able to be arranged in a form-fitting and / or force-fitting manner in the guide receptacle. Such fixing means can thus be used to fix the locking element in its fastening position, which, in other words, can inadvertent and / or accidental removal of the locking element from its fastening position and thus a loosening of the fastening of the housing on the mounting plate can be prevented. Such fixing means can be actuated from outside the housing, as a result of which it is possible to grip the fixing means or to actuate the fixing means even when the housing is placed on the mounting plate. The fixing means can also preferably be designed as threaded pins, which can be arranged, in particular screwed, in the guide receptacle, for example, in a form-fitting and / or force-fitting manner. In particular, this screwing or arrangement in the guide receptacle can be particularly easily and safely prevented from moving the locking element mounted in the guide receptacle. For this purpose, the guide receptacle can preferably be formed at least in sections with an internal thread.

According to a preferred embodiment of a fitting according to the invention, it can further be provided that the guide receptacle is arranged on and / or in the mounting plate and the latch receptacle is arranged on and / or in the housing. In other words, the bolt receptacle is arranged in that element of the fitting that is arranged first on the door or the window. Following the secure fastening of the mounting plate to the door or the window, the housing is placed on the door and fixed to the mounting plate by moving the locking element which is displaceably mounted in the bolt receptacle. In this case, a drive unit can particularly preferably already be arranged in the housing, so that after fitting the housing and fastening the housing to the mounting plate, assembly of the fitting according to the invention is at least substantially completed.

A fitting according to the invention can preferably be developed in such a way that the mounting plate has two guide receptacles, preferably arranged at opposite ends of the mounting plate, and that the housing has two locking receptacles, preferably arranged at opposite ends of the housing. In this way, a double fixation of the housing on the mounting plate and thus an increase in the security of the fastening of the housing on the mounting plate can be achieved. In addition, it can particularly preferably be provided that the two locking elements in the guide receptacles for engaging in the respective locking receptacle, particularly preferably for assuming the respective fastening position, in at least substantially opposite directions in the respective leadership admission be postponed. With an arrangement of the two guide receptacles at opposite ends of the mounting plate, the two locking elements can thus preferably be moved toward one another in order to assume the respective fastening position. This counter-moving movement of the two locking elements can further increase security when fastening the housing to the mounting plate, since this also requires an opposite movement of the two locking elements to completely loosen the fastening. An unwanted and / or accidental loosening of the attachment of the housing on the mounting plate can be made more difficult in this way.

A fitting according to the invention can also be further developed in that the locking element has an actuating section for manual displacement of the locking element. Such a manual shift represents a particularly simple type of actuation for producing the fastening of the housing on the mounting plate. In particular, no tool, in particular no special tool, is necessary for this manual shift. The fastening of the housing to the mounting plate of a fitting according to the invention can thus be made mechanically even simpler and in particular more user-friendly or user-friendly.

The actuating section is particularly preferably designed like a frame or has a through opening. Such a frame-like design or the provision of a passage opening can further simplify manual displacement of the locking element. In particular, actuation by simply engaging in the frame of the locking element or in the access opening can bring about the manual displacement of the locking element in a particularly simple manner. In addition, such a passage opening can also allow access to the interior of the housing after the housing has been fastened to the mounting plate, for example for connecting an electrical drive unit in the interior of the housing.

A fitting according to the invention can also be designed such that the guide receptacle and / or the bolt receptacle has an end stop for positively locking the bolt element in its fastening position. In other words, when the locking element reaches its fastening position, in which it engages in the fixing section of the locking receptacle as described above, it forms a positive contact with the end stop and thereby stops. A safe assumption of the fastening position of the locking element can be ensured in this way. In particular, such an end stop can prevent the locking element from being displaced to such an extent that it leaves the fixing section of the locking receptacle again. The end stop can particularly preferably be provided, for example, by a closed end of the bolt receptacle or the fixing section of the bolt receptacle.

Furthermore, a fitting according to the invention can be further developed in that the guide receptacle and / or the latch receptacle has an intermediate stop for the positive and / or non-positive indication of an arrangement of the latch element in its release position. Such an intermediate stop can be formed, for example, by a small projection in the guide receptacle and / or bolt receptacle, the expression small in the sense of the invention meaning, for example, that the user can feel that the intermediate stop has been reached when the locking element is actuated or moved manually is, the intermediate stop can be overcome at the same time by a slight increase in the force applied. In particular, such an intermediate stop enables the locking element to be used for displaying or safely assuming the release position. This can be particularly advantageous if there are recesses in the housing, which are provided as part of the bolt receptacle for receiving the bolt element in the bolt receptacle before being moved into the fixing section of the bolt receptacle.

A fitting according to the invention can also be developed in that the housing is designed to accommodate a, preferably electrical, drive unit. Such a drive unit, in particular an electrical drive unit, can be used to electrically move or actuate the corresponding window and / or the corresponding door. Particularly preferably, the corresponding drive unit can already be pre-assembled in the housing before the housing is connected to the mounting plate via the locking element for the fitting according to the invention. In this way it can be made possible that an entire assembly of a fitting according to the invention is at least essentially completed after the housing has been attached to the mounting plate.

Furthermore, it can be provided in the fitting according to the invention that the fitting has at least one cover element for covering the end face of the mounting plate, preferably additionally of the at least one locking element and / or the housing. Such a cover element allows access to the locking element, in particular unauthorized access to the locking element, become more difficult. Such a cover element, in particular if it additionally covers the locking element and / or the housing, can also achieve an attractive appearance of the entire fitting.

In a fitting according to the invention, it can also be particularly preferred that the mounting plate and / or the housing and / or the locking element is designed as an extruded profile, in particular made of aluminum. Such extruded profiles are easy to manufacture in large quantities. In this way, manufacturing costs for a fitting according to the invention can be reduced.
